hi Klemen!

is it not possible for u32 bit images? instead of u8?

Hello,

yes, it is possible. U32 image has 3 color planes + alpha channel (3*U8 + 1*U8 = U32). You just need to extract the correct plane (in the appropriate color space) and you are performing your operation on U8 again

See the attached code.

Alternatively, you could also use "IMAQ ColorBCGLookup VI", where the lookup table is applied to red,green and blue plane seperately.

Best regards,
